Week 7 — Readings & Resources

Human Anatomy and Physiology I Free sample edition

Your primary reading is Chapter 7 (in this module). Everything below is the optional, go-deeper layer — pick what helps, skip the rest.

How to use this page

This page has 10 items (4 readings and 6 videos). Allow 62–72 minutes for everything. Each group points back to the matching chapter section and class-session segment, so use the full menu when you want more, or take the quick path below.

Every video here has captions: turn them on with the CC button in the player. The chapter covers the same ideas in text.

Pick-one quick path (19–21 min total)

① Is bone really alive?

Chapter 7, Section “Meet a living tissue: bone is not dead mineral” · Session 1, Segment 1, “Bone is a living tissue” · Remember: bone holds blood vessels, nerves, and cells inside its hard matrix, and it thins when it carries less load.

The Skeletal System: Crash Course Anatomy & Physiology #19 — CrashCourse — a fast, well-paced episode that opens with astronauts losing bone in orbit, then sorts bones by shape, compares compact and spongy bone, zooms into the osteon, and ends on the cells that remodel bone; use it as a tour of the whole week before you read closely. (video, 11 min) (captions: creator)
You're Losing Bones Right Now — SciShow — a short explainer on why your skeleton is being broken down and rebuilt all the time; listen for the two kinds of cells doing the work, and treat any figure it gives as an estimate rather than a number to memorize. (video, 5 min) (captions: creator)
Musculo-skeletal system: Bone and Muscle loss — European Space Agency — a short space-agency page on why weightless astronauts lose bone, with weight-bearing bones losing the most; read the bone-loss section, notice that its monthly estimate differs a little from the chapter's, and treat both as estimates. Use it while completing the Week-7 module overview. (reading, 2–4 min)

② Reading a long bone, outside and in

Chapter 7, Section “Read a long bone: shaft, ends, and the hollow center” · Session 1, Segment 4, “Reading a long bone” · Remember: the diaphysis is the shaft, each epiphysis is an end, and a cut across the shaft reads periosteum, compact bone, endosteum, medullary cavity.

Bony Tissue: Anatomy of a Long Bone — Dr Matt & Dr Mike — a walk through the anatomy of a long bone and its tissue; pause after each part and say what it is and where it sits, the way the chapter reads it end to end. (video, 8 min) (captions: automatic)
Skeletal System Overview — Armando Hasudungan — a hand-drawn overview of the skeleton; keep to its jobs, its shapes, and a long bone's parts, and leave any named bones of each region for later in the course. (video, 6 min) (captions: automatic)
Cartilage and Bone — Histology Guide — the free virtual microscope's chapter on cartilage and bone; open one compact bone slide and look for rings around a central canal, then open the cancellous and compact bone slide and find the lattice of trabeculae, and skip the cartilage slides. (reading, 8–12 min)

③ Growth plates and the calcium loop

Chapter 7, Section “Run the loop on calcium: parathyroid hormone and calcitonin” · Session 2, Segment 9, “The calcium loop” · Remember: parathyroid hormone stimulates osteoclasts to raise blood calcium, and calcitonin inhibits them to lower it.

Calcium Homeostasis: Parathyroid Hormone and Vitamin D — Dr Matt & Dr Mike — a short explainer on how the body holds blood calcium steady; listen for parathyroid hormone sending calcium out of bone, and note that its vitamin D and kidney details go beyond this course. This builds on Week 1's work with the feedback loop: name the receptor, control center, and effector as you watch. (video, 4 min) (captions: automatic)
Bone Homeostasis (Calcium and Phosphate) Hormones — Armando Hasudungan — a longer hand-drawn walk through the hormones that move calcium and phosphate in and out of bone; keep to parathyroid hormone and calcitonin and what each does to osteoclasts, and skip the phosphate details, which go beyond this course. (video, 10 min) (captions: automatic)
Growth Plate Fractures — OrthoInfo — a plain-language page from a professional body of bone surgeons on the growth plate, the cartilage near each end of a long bone where it lengthens; read the opening anatomy section and stop before the classification and treatment sections, which go beyond this course. (reading, 4–6 min)

Optional one-stop reference (free online reference)

Structure of Bone Tissue — SEER Training Modules, National Cancer Institute — the course's free online anatomy reference, open at its page on compact and spongy bone and the bone cells; read the two texture sections and the cell list, and skip the cancer-registration material elsewhere on the site. (reading, 4–6 min)

Heads-up (links rot): these point to outside sites that occasionally move or rename pages. If a link ever fails, tell your instructor and use the reference above in the meantime.
